Recent Developments in Underground Metal Mining.

The goals of the metal mining research program at the U.S. Bureau of Mines are to increase productivity, improve safety, and prevent and remediate mining-related damage. Achieving these goals requires a systems approach to the entire life cycle of mining, beginning with conceptual design of a mine and ending with a final closure and reclamation plan. Some recent achievements in this program include advances in mine design technology; better ground control techniques, including the use of flexible tendons (cable bolts); increased production through automation and improved drilling technology; and alternative forms of mining, such as in situ leaching. Cooperative research and cost sharing with the mining industry are helping to transfer the new technology developed during the pursuit of these goals.
